Plenty of amateur films have been shot using iPhones, but by all reports, this is the first movie at the Sundance Film Festival to be shot almost entirely on an Apple device. It was a decision that indie writer and director Sean Baker made to accommodate the film’s small budget. But you’d never guess the camera, to look at it: Tangerine was shot in a widescreen, 2:35:1 aspect ratio, and its camera zooms through the streets of LA with a fluidity you’d never expect from a handheld device. And yet despite his camera of choice, Baker says the iPhone made for a good partner. "It was surprisingly easy," Baker says. "We never lost any footage."
